TRANSFORMADORO transformador permite conexo rede eltrica.B. FONTE DE ALIMENTAOA fonte de alimentao consiste de retificadores, capacitores de filtro e reguladores de tenso. As tenses reguladas incluem+5V6, +LED,+12A, +12M, -32V, PWDN.A tenso +C para o amplificador de potncia no regulada.F1-F2 a alimentao para o filamento do Display FTD.C. SELEO DE ENTRADA & AMPLIFICADORa) SHIFT REGISTER (CONTROLE DE AF)O shift register encaminha comandos do MP para controlar as funes de AF que incluem seleo de entrada (linhas de controle A0 & A1),modos DSC, DBB, IS e CD_ON (vias +CD). Outras linhas de controle como MUTE, AMPON, STBY e PWM vem diretamente do MP nono Painel Frontal. b) SELEO DE ENTRADAUma das 4 entradas, AUX, TAPE, TUNER e CD, podem ser selecionadas via linhas A0 & A1 que controlam o IC 7501(HEF4052BP). O microfone de Karaoke conectado ao amplificador de sinal (Tr 7503 & 7504). O sinal ento separado em, caminho de gravao (para gravao em fita) e ao caminho do sinalprincipal (ao controle de volume PWM).c)CONTROLE DE VOLUME PWMO controle de volume utiliza 4 Transistores 7505, 7506, 7507 & 7508 (ON4986 ouBC557B casados) e sinal de controlePWMdoMP.
